Abstract
In an electronic apparatus of this invention, after a security function is canceled, it is determined whether the elapsed time from cancellation of the security function to detection of attachment of a device having a security function of security level higher than that of the canceled security function or the elapsed time until the operation of the attached device is enabled has exceeded a predetermined time. Upon determining that the elapsed time has exceeded the predetermined time, the electronic apparatus enables the canceled security function again.
